Who coined the term 'Kinetin'?

Options

A. Skoog and Miller
B. Darwin
C. Went
D. Kurosawa

Answer

**Step-by-Step Solution:**

1. **Understanding Kinetin**: Kinetin is a type of plant hormone known as a cytokinin, which plays a crucial role in promoting cell division (cytokinesis) in plants.

2. **Historical Context**: The term 'Kinetin' was coined during research conducted by scientists who were studying plant hormones and their effects on plant growth.

3. **Key Scientists**: The primary scientists involved in the discovery of Kinetin are Frederick C. Steward, Folke Skoog, and Miller. They conducted experiments that led to the identification of this substance.

4. **Experimental Findings**: Skoog and Miller observed that when they added certain extracts (like those from yeast or coconut milk) to a nutrient medium containing auxin (another plant hormone), they could induce the proliferation of callus tissue from tobacco stems.

5. **Crystallization and Naming**: Through their experiments, they were able to isolate and crystallize the active substance responsible for promoting cytokinesis, which they named 'Kinetin'.

6. **Conclusion**: Therefore, the term 'Kinetin' was coined by Skoog and Miller based on their research findings.

**Final Answer**: The term 'Kinetin' was coined by Skoog and Miller.
